An Dunscaja120 days, indeterminate — The plants that grow thirty four to thirty nine inches tall, with white flowers, and pods holding two to three seeds each. The seeds are medium-sized, flattened and elongated in shape. They are tan in color with a black "saddle" that sometimes nearly encircles the entire seed. The result is that some beans look to be almost all black in color. They contain about 46% protein and 18% oil.

The USDA accession number is PI 437815 and it was originally collected in Northeast China and donated in 1979 by N. Korsakov, of the N. I. Vavilov Institute of Plant Industry. Each packet contains 25 to 30 seeds.
